Meet the site
North Sno is a site on North Opal Reef that Scuba IQ describes as less dive site, more moonscape, with an open topography and typically excellent visibility of 30 m plus. It is a very different experience from the coral-packed bommies and walls elsewhere on Opal. The terrain is wide and open – scattered coral outcrops, rubble and sand rather than a continuous reef wall. That openness, combined with clear oceanic water, gives the dive a spacious, almost otherworldly feel. You can see a long way in every direction, which makes it a good site for spotting larger animals such as reef sharks, rays and turtles as they cross the open ground. Scattered coral heads host reef fish, and the sand patches hold gobies, shrimps, garden eels and sometimes stingrays. The site rewards divers who enjoy exploring and looking for animals at a distance rather than inspecting dense coral up close. Scuba IQ does not publish depths; most of the dive is likely to be in the 10–18 m band. Navigation can be challenging in open terrain, so staying with the guide is advisable. North Sno suits divers who want a change of pace and appreciate visibility – on a calm day it offers some of the clearest water on the Port Douglas reefs. It is also a great site for wide-angle photographers looking to capture the scale of the reef and the clarity of the water. Because the name is used mainly by Scuba IQ, ask for it by name on a small-group day; larger boats may not use this mooring at all, and the final choice always depends on wind and tide.
